dont listen to what people say about 123A batteries, for a newb or casual flashlight user, AAs are much better, specifically eneloops and a spare pack of Lithiums for emergencies. I would recommend the Fenix LD10, LD15, or LD20 R4, or Quark AA or AA2, with a set of 4 or 8 Sanyo Eneloop or Rayovac Hybrid batteries w/ charger, and a set of 8 or more Lithiums for emergencies. Lithium batteries in AA size are about as efficent as 123A, but cost a little more. The advantage is you can use rechargable NiMH or NiOX batteries, which are cheap, effective, and last quite a long time. The best cost under $10 a pair and chargers are under $25. with value like this, you can rely on these batteries for years before youll need another set, and you can always use Alkalines if you run out of all other options.
Some things to keep in mind:
* Brighter isnt always better. I have a 45 lumen light with regulated output. It easily compares to a Mag 3D incandescent, and doesn't yellow as the batteries weaken. For a everyday light, 60 lumens or more is fine. Durability and price and runtime are more important.
* For small lights, its usually best to get more flood then throw, as throw is really only super useful with lots of lumens to back it up. All lights I recommend have a good balance.
* Remember to consider prices of batteries and shipping. Lithium 123As cost $1-2 each whereas NiMH rechargables are $5-10 and are rechargable over and over again, unlike lithiums. Lithium AAs are around $4 a pair in electronics stores, compared to $10 a pair for 123As. Online, both are cheaper, 123As about $2 each or less, Lithium AAs $1.75 each or less.
Alkaline AAs are of course very cheap, but runtime is less than half that of lithiums and considerably less than NiMH. Nevertheless, a good last resort option to have, and if you plan on traveling, alkaline AAs are the battery you can find pretty much anywhere, and cheap to boot, unlike any other type.
If you want a real durable light, that you can take anywhere, and price is no concern, consider the Surefire E2L-AA. Otherwise, the best value and durability lies in 2xaa lights like the Quark AA2 R5, Fenix LD20 R4, and Eagletac P20A2 Mark II. 1XAA lights are also acceptable, and the best in that class are the Fenix LD15, LD10 R4, and Quark Mini AA for just $39.99. The NiteCore D11 is also coming out soon and looks to be decent.
Its a great time to be a light addict, and one light can do all your needs now if it must. Welcome! :wave:
